[0027] See also Figure 2-6 The present invention provides an embodiment: a method for using a magnifying glass application system with a positioning structure, comprising the steps of: first, system initialization; second, image input; third, text recognition; and fourth, area magnification.

[0028] In step 1 above, the user sets up the image matching template in the system, including the text area to be recognized and various attribute settings, and also sets the scanning parameters, including DPI, etc.

[0029] In the above step 2, the user uses a scanning terminal to scan an image, and the image input module 1 transmits the image to the image processing module 2;

[0030] In the above step 3, the image processing module 2 normalizes the image to the set DPI, and the text recognition module 3 recognizes the text in the specified area;

[0031] In the above step 4, the user enters the information verification and metadata entry interface. When the user views the metadata text area, the area type judgment module 4 judges the area type, and the area coordinate return module 5 returns the area coordinates based on twips to the positioning magnifying glass module 6 according to the judgment result. The positioning magnifying glass module 6 processes the area coordinates and outputs the optimized display area through the optimized display area output module 7. The area will be dynamically enlarged and placed in the visual area for the user to view. The specific method for the positioning magnifying glass module 6 to process the area coordinates is as follows: the area coordinates based on twips are transmitted from the area coordinate input submodule 60 to the coordinate conversion submodule 61.

After algorithm processing, the optimized display area can be output by the optimized display area output module 7.

[0032] Based on the above, the advantage of the present invention is that when the present invention is used for image and text recognition, the image input module 1 enters the image data into the system, and after pre-processing by the image processing module 2, the text recognition module 3 recognizes it. When the user views a certain area, the area type judgment module 4 judges the area, and the area coordinate return module 5 returns the area coordinates based on twips to the positioning magnifying glass module 6 according to the judgment result. The positioning magnifying glass module 6 optimizes the area coordinates based on twips and can directly obtain the optimized display area. The entire optimization process does not require human intervention, which greatly reduces the user's repetitive and inefficient operations, saves working time, and significantly improves the user's work efficiency.
